TAS5615DKDR

Overview

The TAS5615DKDR is a high-performance analog input Class-D audio amplifier manufactured by Texas Instruments. It utilizes integrated closed-loop feedback technology to drive up to 160 W of stereo power into 8-ohm speakers from a single 50-V supply. The device supports signal bandwidths up to 80 kHz, ensuring high-fidelity audio reproduction. It is housed in a 44-pin HSSOP package designed for surface-mount installation.

Feature Summary

• Integrates PurePath HD closed-loop feedback technology for enhanced audio fidelity
• Supports high signal bandwidth up to 80 kHz for accurate sound reproduction
• Capable of delivering high-power stereo output from a single voltage supply

Applications

• High-end home theater systems
• Professional audio amplification equipment
• Premium consumer electronics requiring high-fidelity sound

Procurement Notes

Verify the specific suffix DKDR against the official Texas Instruments datasheet to confirm the package type and reel configuration. Ensure compatibility with the intended PCB footprint and thermal management requirements. Confirm current availability status as distribution channels may vary. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when high-power stereo amplification is required from a single supply rail. The integrated closed-loop feedback makes it suitable for applications demanding low distortion and high signal integrity. Consider the 44-pin HSSOP package constraints during layout design. Evaluate thermal dissipation needs given the 160 W output capability.

Part Context

This component belongs to the TAS5615 series of Class-D audio amplifiers. It is distinct from digital-input variants like the TAS5614A or higher-power models such as the TAS5631. The TAS5615 specifically targets analog input applications where pure path HD technology provides superior performance compared to open-loop designs.
